From Frenchbigot(“a sanctimonious person; a religious hypocrite”), from Middle Frenchbigot, from Old Frenchbigot, of uncertain origin. It is often thought to derive from an Old French derogatory term applied to the religious Normans, said to be known for frequently swearing "by God" (compare Old Englishbī god, Middle High Germanbī got, Middle Dutchbi gode); compare the French use of "goddams" to refer to the English in Joan of Arc's time. Liberman however thinks this has "too strong a taste of a folk etymological guess invented in retrospect" and prefers Grammont et al.'s theory that it derives from Albigot(“Albigensian heretic”).[1]
